Diethylmethylammonium methanesulfonate, CAS: 945715-44-6

Key Applications:

Electrochemical Systems & Ionic Transport Studies

• Serves as a low‑volatility ionic medium for evaluating ion transport, conductivity behavior, and charge‑transfer mechanisms in electrochemical devices.
• Used in prototype electrolyte formulations for capacitors, redox systems, and emerging low‑temperature electrochemical platforms.
• Supports mechanistic studies on ion–solvent interactions, dielectric relaxation, and structure–property relationships in ammonium‑based ionic liquids.

Catalysis & Reaction Engineering

• Functions as a non‑nucleophilic, thermally stable ionic environment for acid‑catalyzed and transition‑metal‑mediated transformations.
• Enables rate enhancement and selectivity tuning in esterification, alkylation, and dehydration reactions due to its strong ionic character and low coordinating ability.
• Employed in green chemistry workflows where replacement of volatile organic solvents is desired.

Separation Science & Extraction Media

• Utilized as a task‑specific ionic liquid for liquid–liquid extraction, particularly for polar organics and metal ions requiring a stable, hydrophilic medium.
• Supports chromatographic method development, including stationary‑phase modification and mobile‑phase tuning for enhanced analyte resolution.

Polymer & Materials Processing

• Acts as a processing aid and plasticizing ionic additive for specialty polymers, ionomers, and conductive composites.
• Useful in polymer dissolution, dispersion, and surface modification where controlled ionic strength and low volatility are required.
• Supports fabrication of ionically conductive films and membranes for sensors and soft‑material electronics.

Sustainable & Alternative Solvent Systems

• Provides a non‑flammable, low‑VOC solvent platform for environmentally conscious process development.
• Applied in biomass fractionation, carbohydrate dissolution, and mild pretreatment workflows where ammonium‑based ionic liquids offer compatibility with biopolymers.

Thermal & Stability Studies

• Used as a model compound in thermal decomposition, viscosity, and phase‑behavior research on ammonium sulfonate ionic liquids.
• Supports development of predictive models for ionic liquid stability, solvation, and physicochemical tuning.
